Hide Taskbar in Windows 8

Question

Up to now, I was able to use the following C# code to hide the Windows taskbar:

[DllImport("user32.dll")]
private static extern int FindWindow(string className, string windowText);
[DllImport("user32.dll")]
private static extern int ShowWindow(int hwnd, int command);

private const int SW_HIDE = 0;
private const int SW_SHOW = 1;

...

int hwnd = FindWindow("Shell_TrayWnd", "");
ShowWindow(hwnd, SW_SHOW);

But when using Windows 8, this code only hides the taskbar on the primary monitor, not on the second, where the taskbar is also visible.

How may I hide the taskbar only on the screen where my windows are being shown?

Answer 1

Don't hide the taskbar; that's the wrong way to do something like this. Instead, just make a fullscreen window, and the taskbar is smart enough to get out of your way.

You can read a good explanation & commentary by Microsoft's Raymond Chen on his blog.
